1. Plot Summary
Set in a remote, rural region of Argentina, When Evil Lurks begins when brothers Pedro and Jimi hear gunshots near their land and later discover a gruesome, disemboweled corpse. Their investigation leads them to a family hiding in a shack, including a boy, Uriel, who is possessed by a demonic force and referred to as “the Rotten.”
As the brothers attempt to rid Uriel of the demon and protect their community, they must navigate strict rules of exorcism, missteps that propagate possession, and growing chaos as the infection spreads to livestock, neighbors, and even children. The film follows their descent into a nightmarish ordeal where traditional logic fails and survival becomes a desperate, violent struggle.
2. Notable Elements
Strengths / Highlights
- Atmosphere & dread: The film creates a suffocating sense of dread more via implication, silence, and visual tension than overt gore. Many scenes linger just at the edge of revelation, which heightens unease.
- Practical effects & makeup: The possessed / “rotten” characters display grotesque, unsettling visual design—oozing flesh, contorted forms—executed with strong practical makeup and effects.
- Performances: Ezequiel Rodríguez (Pedro) carries emotional weight, especially in scenes of desperation. The supporting cast (Silvina Sabater as Mirta, Virginia Garófalo as Sabrina) provide memorable moments, especially when the supernatural intersects with human frailty.
- World-building & lore: Rugna unfolds rules of demonic possession gradually—don’t kill via gun, avoid spreading contamination, obey bizarre commandments—creating a fresh mythology rather than rehashing standard exorcism tropes.
- Visual storytelling: Moments such as children becoming possessed, or the reveal of the demon’s birth, are haunting images that linger. While some critics point out that the second half overexplains, the film still delivers striking, unforgettable sequences.
Weaknesses / Critiques
- Heavier exposition in second half: Several reviewers note that the first half’s subtle, ambiguous tension gives way to more overt explanation and narrative handholding in the later sections, which somewhat undermines the mystery.
- Narrative leaps / logic gaps: The film introduces many rules of possession, but some are not consistently followed or fully realized in action. For instance, the way the autistic young boy plays into resistance against possession is controversial in execution.
- Character depth trade-off: With the focus on horror and mythology, less time is spent on character backstory or emotional arcs for some secondary characters. Some sacrifices or events feel driven more by plot necessity than organic development.
3. Themes and Messages
- Infection & contagion: When Evil Lurks frames demonic possession more like a contagion—mistakes in handling it lead to wider spread, reinforcing that fear, ignorance, and rash action enable evil more than the supernatural itself.
- Human fallibility & superstition: The film highlights how in rur al or isolated communities, superstition, half-understood rituals, and half-beliefs dominate decisions—often disastrously.
- Family, guilt, protection: Pedro’s efforts to protect his family (kids, ex, brother) under ever escalating horror show how love and fear collide in crisis.
- Limits of rationality: As events spiral, logic fails; faith, ritual, and desperation take over. The movie questions whether rational explanations can combat a force that escapes rational bounds.
- Sacrifice & inevitability: Several characters must face that not all can be saved; the film doesn’t shy from moral compromises.
As for holiday traditions or sentiments: This film is not thematically aligned with festive, hopeful, or warm holiday vibes. It’s dark, intense, catastrophic. The only possible resonance is in contrast: its portrayal of fear, loss, and urgency can sharpen one’s appreciation for safety, family, and peace during holiday times.
4. Personal Impressions
What worked for me:
- The first half truly grips with its slow burn. I felt tension build scene by scene, and I appreciated the mystery rather than immediate clarity.
- The visual horror is effective: I still find some images from When Evil Lurks lingering in my mind (possession of children, the demon birthing moment).
- Rugna’s willingness to resist pure jump-scare horror in favor of unsettling ambiguity is a strength.
- The film has ambition: it doesn’t just scare, it wants to create a mythos, a set of rules, a logic to its own evil.
What bothered me somewhat:
- When the exposition kicks in, I felt some of the mystery was lost. The film sometimes overexplains what had been more powerful when left ambiguous.
- Some narrative choices (e.g. about the autistic boy’s role, or how the possession spreads) felt like convenient twists rather than grounded developments.
- On rare occasions, the pacing dips, particularly when the film pauses to explain lore or set up final confrontations.
5. Audience Recommendations
Who will especially enjoy it:
- Fans of cerebral horror / demonic possession stories who appreciate mythology, rules, and ambiguity rather than simple scares.
- Viewers who like slow-burn tension and don’t mind being challenged or unsettled.
- Horror aficionados who appreciate strong practical effects, grotesque transformations, and memorable imagery.
- Fans of international horror, especially Latin American directors and dark supernatural tales.
Who might dislike it:
- Those who prefer straight horror with clear explanations or a “safe” ending.
- Viewers uncomfortable with gore, body horror, or disturbing content involving children.
- Audiences who need deep character arcs or emotional resolution for every character; When Evil Lurks sometimes leans more on atmosphere and myth than emotional closure.
6. Conclusion & Rating
When Evil Lurks is a compelling, daring entry in modern horror. It doesn’t always deliver on every narrative promise, but its strengths—atmosphere, lore, unnerving visuals—carry it far. If you’re in the mood for a horror film that will haunt your thoughts more than just your night, this is one to watch.
Final Recommendation: Highly recommended for serious horror fans seeking something bold, disturbing, and memorable. Be ready for a ride that doesn’t always tie every thread neatly, but often rewards in mood and imagery.
